How do you say shut up in Southern slang?

Excuse me, I'm curious to know how one might express the phrase "shut up" in the colloquial language of the Southern United States. I understand that regional dialects can vary greatly, and I'm particularly interested in the way that this particular phrase might be phrased in a Southern accent or slang. Could you provide me with an example or two of how someone from the Southern region might say "shut up" in conversation?
